My invention relates to a bassinet organization adapted for the care ofinfants, particularly new born babies, andhas for its object to providein an easily accessible and convenient form anadjustable means ofsupporting the infant in desired positions, meansf'or properly tempermgthe bed on which the infant lies and the atmosphere surrounding theinfant and for giving to it a suitable moisture content, means forwithdrawing saliva or other accumulations from the mouth and otherpassages of the infant, means for giving to the infant an atmospheresuitably enriched with oxygen, andresuscitation means including oxygensupplying means for bringing about and establishing correct breathing bya new born infant threatened wtih asphyxiation from breathing failure.

A percentage of infants are born which, either have a very precarioushold upon life and require special treatment of the most prompt andeffective kind in order to be kept alive. Somebecause of premature birthor for other causes, I

times the breathing doestnot establish itself and asphyxiation .impends.Under such conditions not only must resuscitation means be promptlyapplied to establish breathing but it must be under conditions where theleast shock can result and under conditions where the proper temperatureand humidity of surrounding atmosphere free from drafts will be presentand at all. times available. And in other cases, where breathing hasbeen establishednormally but from other causes the life of an infantisthreatened,

. ganization embodying my improvements thereto.

similar conditions of freedomifrom shock, suitable support for theinfant in an atmosphereof proper temperature and humidity and suitablyoxygen-enriched, are called for. i

It. is: a principal object or my invention, there fore, to provideabassinetl organization includ ing the means broadly stated above,whereby an infant born in an abnormal condition from any cause so that.extinction or life is. threatened, can be immediately positioned where.shock is avoid-V ed, and any and all. of the instmmentalities forbringing it to normal condition are.v conveniently andimmediatelyavailable.

In carrying out my invention herein described and claimed I haveemployed among. other things the resuscitation. apparatus of patents toRobert B; SWOpe; and myself, Numbers: 1,848,232, 1,848,233 and1,848,234,. allgran-ted on. March.- 8, 19-32; for

resuscitation apparatus; and. special inhaler used therewith, incombination. with a. bassinet chamher with means for adi-usting; thepositioning of the infant therein and variousrinstnwnentalie ioia m,(01. 128-1) 1 ties for supplying oxygen, properly heating andhumidifying the atmosphere within the bassinet chamber and supplyingoxygen to the f infant where that is called for.

Thefull objects and advantages of myinvention will appear in connectionwith the description given in the following specification and the novelfeatures by which are obtained the valuable and advantageous resultsabove referred to will be particularly pointed out in the claim.

suitable porous material, which is enclosed within a. cover member 21,whereby the infant supportingmember itself as well as the space above itare suitably heated. The support 24 is pro-'-' vided with a pair of pins28 which are adapted to engage angle iron shelves 29 and 36 secured tothe side walls I I and I2 upon which the entire assemblage maybe rockedto put the supportin pad 26in any desired angular position. 'This memberis held in adjusted position by means of a finger 3|, Fig. 4, which goesthrough'a slot 32 in end wall I4and takes in the notches 33' along saidslot, Figs. 2 and 3. Similarly the lower end of the mesh support 24 isprovided with a finger member 34 which takes into a similar slot andnotchesinot shown) to adjust the member 24 and the hinged part 24'indifferent angular positions relative to the part 24.

. This arrangement is such that thebabys support as a whole may bedisposed at any desired angle to the horizontal and the portion 24thereof may be disposed at any desired angle to the portion 24. At thesame time the entire arrangement is such as to permit the reception ofheat from below the pad 26. A cover 35 is normally placed over the rearportion of the'compartmenti 22, as'best shown in Figs. 1 and 12. Thiscover tends to retain heat toward the foot of thegbaby holdingcompartment of the bassinet while the part at the front, as indicated inFig. 12, is open neitherto' the fair of the room or to an'oxygen tent 36which will be later described in detail To furnish the heat aboveindicated an electric heating element 31, as best shown in Fig. 5, iscarried in a substantial rectangle underneath a series of guard plates38, 39, 40 and M, located in the lower part of chamber 22, as clearlyshown in Fig.3. The guard plates above referred to receive thedirect-radiation from the heating element 31. This effects heatinglargely by convection, which keeps the outside walls warn, thuspreventing cold drafts, and dissipates theheat throughout the bottomportion of the chamber from which the heat rises to pass, through theopen mesh supporting members 24,

24' and through and about the supporting pad As shown in the wiringdiagram of Fig. 14 the mainsupply current wire 42 goes to the heatingelement 21. A branch wire 43 goes through a mercoid switch 44 from whichleads a second branch wire 45 which passes through manual switch 46 tothe second main current supply wire 41. The mercoid switch is locatedwithin a thermostat control box 48 which is closed by acover member 48which gives access to the interiorithereof. Th'e thermostat is of awellknown gas expansion type wherein the expansion member 50 isconnected by a tube 5| with a diaphragm chamber 52 adapted to move apiston head 53 into engagement with a lever arm 54 which has a long arm55 adapted to rock the holder 56 for the mercoid switch 44 to turn thewhich the infant lies and the atmosphere above the infant to a desiredtemperature. When this part of the chamber is employed for receiving aninfant just born this temperature of the pad upon, which it is to belaid and the atmosphere surrounding it should be substantially that ofthe body temperature surrounding it before birth, that, between 98 and99 F.- It has-been found that to produce this temperature at thesupporting-surface of the pad and in thelatmosphere above it, a maximumtemperature below the pad and controlledby the thermostat should bearound F. a I 1 Under most conditions, except when the apparatus, isused for resuscitation purposes, an

oxygen tent 62.will be employed and have suitably tempered oxygendelivered thereto. The oxygen tent is shown in detail in Figspl and 8.The tent comprises a top -63-formed of rigid material with. doubleflange members64 which support a set of flexible walls .65 adapted toex-v tend through the open portion 66 at -the front of the bassinet, asindicatedin Fig.1. A loop I32 is formed at the bottoms of the tent wallsin which is inserted a formed wire I33 whichholds the bottom of theoxygen tent in position within chamber 22. The severalwalls'of theflexible tent portion are provided with'transparent portions '6'! whichgives the nurse a'ready view of the infant within the chamber 22 of thebassinet.

The top 63 of the tent is provided with a pair'of valveplates I34 andI35Iformedwith sets of openings I36 and I31, Fig. 9." The top plate I34may be rotated bymeans of a handle I38. By

thismeans axventilatingtopaopening of greater or less extent, asdesired,'may be provided. The oxygen. tentiissupported with its openbottom extending a desired distance into chamber 22 by means .of a.tubular member 68 which passes through a clamping" device 69 securedtothe side wall I2 of the bassinet and operatedby means of a thumb'screw'IO whereby the oxygen tent 62 may be held in any desired position asadjusted for height.

The supporting member 68 comprises a tube which is in communication-withan oxygen'de livery tube II extending-for some distanceim side of thetent,- with openings 12 for-permitting flow of oxygen laterally from thetubeinto the tent. A connector member 13 on supporting mem' ber 68,Figs. 1 and 2, customarily is united with an oxygen supply tube I4. fromeither of two tanks 15 or I6 througha regulatingvalve 11 of well knownconstruction. From the valve 11 the oxygen goes by means of a pipe 18,Figs. 1 and 2, to a manifold passage way I9 controlled by avalve 66. Inthe course of its travel from valve 11 along pipe 18 to manifoldpassageway 19 the oxygen may be heated as desired, preferably byelectric heating means, not

. shown. 'From the passageway I9- the oxygen gas passes through'a flowvalve BI and thence through The oxygen is fed a transverse tube 84, Fig.1, and dependingdoop 85 into a valve chamber 86, Fig. 6. A mve 81controls the flow of gas from valve chamber 86 the valve'beingcontrolled by a thumb screw 08;.

In the position or the valve of Fig. fi theoxygen' gas will passdirectly through pipe 89 through openings 90 and'9I into the top of ajar "and from opening SI through an opening 93 which leads to a tube 94connected withthe tube 14 here tofore described. The casting which formsthe valve chamber 96 has secured thereto a container 95 having therein aquantity of water, as indicated at 96 Fig. 6. When the valve 81 is movedby the thumb screw 88 to a position for closing direct connection withpipe 8'9 the. oxygen will flow' through an opening. 91 and a tube 98 todischarge: through a series of apertures 99 into the body of water 96.The oxygen will bubble. through this water and pass through passageway:I to the tube 89. The reversal of the gas through container 92. atpassageways 90 and 9I results' in precipitation of any free water beentrained with the gas bubbles. ar-'- rangement not only supplies oxygengas to the oxygen tent as desired but also suitably humidifies theoxygen and the atmosphere breathed by the'infant. .1

It may be desirable under certain circumstances to deliver fully freeoxygen directly to the patient; For this purpose the tube I4 may bedisconnected from the connector member I3 and connected the infantinhaler IOI, as indicated in Fig. 6, and the oxygen gas either asdelivered from thetank or humidified may be administered directly 'tothe infant. f

Associated with the same oxygen supply and control means as that'whichsupplies oxygen die reot to the oxygen tent or to the infant, is aresuscitator apparatus designated generally by the arrow and referencecharacter I02. This resuscitator apparatus is that of Letters Patent No.1,848,232 and No. 1,848,233, above referred to and need not be describedin detail further than to point out that oxygen is fed to the maincontrol valve I03 through a pipe I04 from the passageway 'I9. Furtherthat the feed of oxygen from the control valve I 03 goesthrough pipe I05to a feed pipe I06 which in turn connects with a flexible tubing I01,Fig. 1, having direct connection with a special inhaler device I08which.fis substantially the same as the inhaler device disclosed inpatent to myself and Swope, No. 1,848,- 232. The pressure of the gasforced under pres,-

sure into the lungs of the infant is controlled by a return tube I09,Fig. 1, which connects with tubing III). The tubing H0 in turn connectsthrough a pipe III, Figs. 2, 3 and 5, which con stitutes the pressure.stabilizing mechanism of the resuscitator I02. This, as described in thesaid patents above cited, includes a column of water adjustable as toheight. -A faucet H2 is adapted to drain off this water.

In the use of this resuscitator apparatus the special inhaler structureI08 is applied ovei th'e mouth and nose of the infant, and lever II3: co1 1- nected therewith is operated to allow oxygen under pressure whichis regulated as a safe pressure toflow into the lungs. The lever H3 isthus released and the doctor or nurse expels the oxygen I by pressureupon the chest and lungs of the infant. In this manner where promptapplication of the resuscitator is made without undue shock, infants,whose life otherwise would quickly end, are resuscitated and saved.

which might.

Under certain conditions it may be necessary to remove from thebreathing passages of the infant accumulations ofslime and mucus, whichunless quickly removed might cause serious and even fatal choking. Inorder to have such an an paratus available for instant use I provide theconstruction indicated indetail in Figs. 1, 10and 11; A valve casing H4is secured to the bottom wall I5 as indicated at H5 of Fig. 11. Withinthe casing are formed an outlet chamber and val-velIi normallyblockingan outlet air passageway III, and an inlet chamber and valve II8normally blocking aninlet passageway I I9. The valve chamber I'I8'extends to a very small opening I leading through the connector neck I2Ito within a collapsible bulb I22. From the inlet passageway II9 leads atube I23 which enters a deposit chamber I24 in a receptacle I'25, asclearly shown in Fig. 10, said receptacle being secured by clampingmeans I 26 to the post I5. From the chamber I24 leads a connectormemberI21 which extends through the cover of the receptacle I some distanceinsidethe same and which is connected by meansof a tube I29 with acatheter suction tube I29. The catheter has secured thereto a loopedmember I30 which is adapted to hang the same upon a hook I3I fast on thebottom wall I5.

With this arrangement the catheter can be inserted into the throat ornostrils of the infant and by successive squeezings of bulb I22 themucus or other clogging matter can be withfor whom any degree of shockmight easily drawn. The valves H6, H8 of course prevent I any undue ordangerous pressure to the throat or mouth passages of the infant uponsqueezing of the bulb. Where desired a small motor building up thedesired negative pressure can 'be employed in place of the bulb I22.

:Among the advantages of my invention particularly to be mentioned arethe provision ofimmediately available means for establishing the life ofa new-born infant and safeguarding the lives of those new-born infantsin any degree subnormal. Under even the best of hospital conditions thenew-born baby comesto light in an atmosphere at a temperature far belowthe temperature under which the infant has lived to the time of birth.Generally speaking, bedding, blankets, or other articles in which theinfant may be wrapped are at that lowered temperature. Contacts with airor other matter at those lowered temperatures are sure to produce adegree of shock. A strong and lusty baby can endure it without tooserious consequences. Not, however, a premature or other subnormalinfant,

prove disastrous.

bassinet organization the new-born infant can be placed upon a supportand in an atmosphere heated to slightly above 98 F. where he willbreathe air or oxygen-enriched air or oxygen at that temperature. Thisavoids that shook which with the premature or subnormal infant mightresult fatally. With the infant whose breathing does not establishitself this avoidance of shock in connection with the use of knownresuscitator appliances tremendously increases the chances that normalbreathing may be established and the life of the infant be saved. I I

But my resuscitator organization also provides the means for sustainingand building up the life forces of prematurely born infants or those whoare subnormal for other reasons. For it contains all of the necessarymeans to treat any condition of a new-born infant or one whose slenderthread of life easily may be snapped thereafter. In this connection theinstant availability of oxygen while the infant is supported upon asuitably heated pad in a suitably heated atmosphere, either for directdelivery to the lungs or breathing of the infant or for enriching theatmosphere which the infant breathes, is of extreme im-.

or all of them may be used with the utmost dispatch while the infant iskept in a condition fully protected from shock. My invention is notmerely the provision of oxygen-supplying means, resuscitator means andthe like, but the provision ofthese means where any or all of them isand .areavailable for instant use upon an infant positioned, warmed andguarded so that any such use will be possible without complicationsresultv ing from shock" caused by other and extraneous conditions. 4 v vlclaimz, I v a H In a bassinet organization, a portable body member.forming an inclosed chamber, porous means therein positioned toward thecenter of the chamber for supporting an infant, thermostaticallycontrolled electric heating means to heat said porous means and tomaintain a predetermined "high temperature within the chamber,a sourceof oxygen supply, an oxygen receiving manifold, means for deliveringoxygen from said supply thereto, means for controlling thedeliverypressure of theoxygen as it is delivered to the manifolcLia set'ofpiping to conduct oxygenfrom the manifold to the chamber for increasingthe oxygen content of the atmosphere normally breathed by the infant,another set of piping for deliveringoxygen from the manifold directly tothe lungs of the infant, said oxygen delivery being effectivesimultaneously through both sets of piping, and means associated withsaid directdelivering means to cause the oxygen therefrom to'
